For a blackbody, the frequency at which maximum energy is emitted is 3 x 1013 Hz:
A. Give a wavenumber for the wavelength of the infrared emission?
B. What is the temperature of the blackbody?
C. What is the total radiance emittance for the blackbody?
D. Consider an emitter (with an emissivity of 0.5) at the same temperature of the blackbody (obtained from B). What is the total power lost by this emitter if its area is 2 m2 ?
The Time Base Control 3 Shows the effect of changing the time base control on the display when there is an input voltage varying in time when the frequency of the voltage is hi
When are intermolecular forces the strongest? Intermolecular forces (dipole-dipole, dispersion and hydrogen bonds). These forces are weaker than chemical (covalent) bonds. Thus
Q The refractive index of a medium is √3. Compute the angle of refraction if the un-polarised light is incident on it at the polarizing angle of the medium. μ = tan i p = √3
